keeps crashing

In the last two weeks or so, photoshop and bridge keep crashing and generating error reports... I'm unable to use either... not sure about the rest of the suite... Not sure what to do... I've uninstalled and re- installed but no luck... mac 3.1, os10.11... Any help would be greatly appreciated. Thank you:)

Mine has been doing this since June. One useful reply was a workaround, set up another user with admin privileges and run it in the new user only. The old user does still crash, I THINK the new user doesn't. Apple checked my imac and said it's in perfect working order, all drivers update along with OS updates when Apple releases them, so it's not the driver issue that some said it must be. Either Photoshop or Apple introduced an incompatibility that sometimes crashes Photoshop and sometimes reboots the Imac.
